摘要
为建立适应东中国海的海浪数值模式,主要基于目前广泛使用的WAVEWATCH ⅡⅠ海浪数值模式进行东中国海海域的海浪数值模拟。以NCEP和NCEP与QSCTAT的混合风场资料为输入,模拟了两个时间段的东中国海海域的海面风浪场。选取的两个有实测资料的输出点分别在渤海和东海。从所得结果来看,使用NCEP与QSCAT混合风场模拟的东海观测点处的波高和风场的观测值和模拟值符合的较好;利用1998年相应时间段的NCEP风场模拟的上述两点结果与实测比较也是可以接受的。研究结果说明,在目前情况下,运用NCEP与QSCAT混合风场建立统一的东中国海海浪数值预报模式是可行的,同时为东中国海波气候学研究及海洋大气耦合作用研究奠定了模式基础。
In this paper we used WAVEWATCH Ⅲ wave model in the East China Sea to set up a proper numerical wave model. We implemented wind field from single NCEP (National Centers for Environmental Prediction) , and combined NCEP and QSCAT wind field in computational domain to simulate wind wave field for two time ranges in East China Sea. The observation spots were distributed in Bohai Sea and the East China Sea, and the WAVEWAICH Ⅲ gave out corresponding output between two points. The results showed that the wave height from the blended field agreed quite well with the obseruations, and also an agreement was shown between the results from NCEP simulation in corresponding time range of 1998 and the measurements of the year. This study indicates that it is,var practical to set up a proper numerical wave model in the East China Sea and lay a model foundation for researchers to study wave climate and coupled sea and atmosphere in the East China Sea.
